The Citrus Greening Bibliographical Database [ http://swfrec.ifas.ufl.edu/hlb/database/ ] managed jointly by the Entomology group at the University of Florida – IFAS in Immokalee and the Florida Center for Library Automation in Gainesville has become a widely used source for information on Huanglongbing (HLB) for researchers, growers, and students throughout the world. The database was designed to centralize relevant information in an accessible, user-friendly interface. It has received over 50,000 visits since its official launch in April 2009, surpassing all expectations. With the help of users and collaborators we are continually adding and updating information and cross-referencing existing data for accuracy. Entries represent worldwide research on the various aspects of HLB: the associated bacteria (Candidatus Liberibacter spp.), the vectors [Diaphorina citri Kuwayama and Trioza erytrea (Del Guercio)], effects of the disease on plants and vectors, and management tactics. This quarter we have concentrated on reviewing and updating existing data for accuracy and functionality. Each of the references was reviewed and every link tested to assure optimal function. We now have 1935 citations, 74% of which are linked to their original sources. Eighty-seven percent of the entries are in English, the remaining 13% are in Spanish, Portuguese, Afrikaans, Japanese, Chinese, French, German, Vietnamese, Dutch, Farsi, Arabic, Czech, and Hebrew. In the last year alone, the database have received over 23,000 visits and more than 60,000 articles have been accessed. The development and use of this project has been presented in several national and international meetings in the U.S and in Mexico. The high traffic and the popularity of the database among researchers and students is in part due to increased exposure thanks to links published by other citrus research and extension webpages (see partial list below). Additionally, the database was promoted in a recent article in Citrus Industry (Arevalo et al., 2010). Our goal for this second year of the project is to continue and improve this service by including the most current information as it becomes available, continually searching for and updating existing documents from researchers around the world, and creating an interactive forum in which researchers and growers can exchange HLB related information.

After a presentation was presented at a meeting of growers and economists at Lake Alfred in April, a new approach was initiated to calculate long-run citrus production projections in Florida. Tree inventory data at the section level (one square mile) was collected from the Florida Agricultural Statistics Service (FASS) and incidence of greening infection was obtained from the Florida Department of Agriculture and Consumer Services office in Winter Haven. These two data sets were merged. There were 3,804 sections in Florida with commercial citrus for the 2009-10 season (FASS). Citrus greening has been found to be present in 1,291 sections or 33.9% of the total. The sections where citrus greening was found, however, had a larger share of the State’s citrus trees. The total number of (commercial) citrus trees in Florida was 74.5 million. The 1,291 sections where HLB was found accounted for 40.3 million trees or 54.0% of the total tree population. Again, not all of these 40.3 million trees have HLB but rather they are in sections where HLB has been found. It was also determined that 78.1% of the sections in the state either have a greening infected tree or is within one mile of a section with a greening infected tree. Despite this finding, analysis of the data suggests that the presence of citrus greening does not appear to have a major effect on citrus production. According to the latest FASS citrus tree inventory, citrus acreage declined by 14,777 acres between 2009 and 2010, a decline of 2.6%. While some of this acreage loss can be attributed to greening, comparison of acreage changes in past years suggests that a stronger effect of greening is lack of new planting. Only 10,332 acres were planted between the 2009 and 2010 survey, which is difficult to compare since annual surveys were initiated in 2008. Another factor complicating production forecasting is adoption by some growers of the foliar feeding approach to managing greening. Although research has been initiated, it is not known at this time how successful this approach might be in terms of reducing tree mortality and maintaining fruit production.
The Citrus Greening Bibliographical Database has a new home and a new face. It can now be found at [http://swfrec.ifas.ufl.edu/entomology/extension/hlb/]. The old address will still connect to the database, however, our clients should update the link to ensure continued access. The database is managed jointly by the Entomology group at the University of Florida – IFAS in Immokalee and the Florida Center for Library Automation in Gainesville and continues to be a widely used source for information on Huanglongbing (HLB) for researchers, growers, and students throughout the world. Entries represent worldwide research on the various aspects of HLB: the associated bacteria (Candidatus Liberibacter spp.), the vectors [Diaphorina citri Kuwayama and Trioza erytrea (Del Guercio)], effects of the disease on plants and vectors, and management tactics. The database was designed to be a centralized source of relevant information with an accessible, user-friendly interface. The database has received 144,272 visits since its official launch in April 2009, and this quarter the website received 33,609 visits. This past quarter, January to March 2011, we continued to add new information to the database and cross-reference all information for accuracy as well as began the development of the interactive Official Facebook Page as a place to invite fellow researchers and growers to HLB related workshops and conferences and where researchers and growers can exchange HLB related information and discuss topics of interest and/or concern. We now have 1,985 citations, 85% of which are linked to their original sources. Eighty-six percent of the entries are in English, the remaining 14% are in Spanish, Portuguese, Afrikaans, Japanese, Chinese, French, German, Vietnamese, Dutch, Farsi, Arabic, Czech, Thai, and Hebrew. This project has been presented to researchers and students in several national and international meetings in the U.S and in Mexico and continues to have increased exposure within the research community through citrus research and extension web pages that have published links to our database (see partial list below). Our goal for the upcoming quarter is to continue to improve this service by searching and uploading the most current information from researchers around the world, continuing to link existing entries to their original documents, and developing the content and marketing of the interactive HLB/Greening Facebook forum.

We now have 2121 citations, 86% of which are linked to their original sources. While the majority of the entries are in English (86%), as the intention of the database is to serve the international research community, the remaining 14% of the entries are in Spanish, Portuguese, Afrikaans, Japanese, Chinese, French, German, Vietnamese, Dutch, Farsi, Arabic, Czech, Thai, and Hebrew. During the last quarter (April to July 2012) there were 227 visits to the home page, 118 of which are new first-time visitors to the site and a total of 5,228 articles were viewed from this database. Seventy-three percent of the visits originated in the US, the remaining 27% visited from 10 countries. We have added new information to the database as well as continued to develop the official Facebook page which continues to expand each month. We now have close to 30 fans of the page. We have also continued to add members to the HLB_database listserv which currently has 16 subscribers. This forum encourages open, dynamic communication among individuals from around the world who have an interest in sharing information on Citrus greening related issues. The project has been presented to researchers and students in several national and international meetings in the U.S, Germany, Brazil, and Mexico and continues to have increased exposure within the research community through citrus research and extension web pages that have published links to our database (see partial list below). Our goal for the next quarter is to continue mining and uploading the most current HLB related information, enhancing the relevance and visibility of the HLB/Greening Facebook page and the listserv service, increase our efforts to connect the international citrus/HLB community, and maintain the high level of data quality by continually checking the data for accuracy and relevance.
